PHP Coding for downloading the image - php

Question

In the website page contains many images with downloading options. If I click the download button it automatically downloaded on user system and it shows on browser downloadable page. I have PHP code like
$image = file_get_contents('http://website.com/images/logo.png');
file_put_contents('C:/Users/ASUS/Downloads/image.jpg', $image);
Above coding is working fine. But I need to provide the path name for image to save. In user side we don`t know the path.
I need the PHP code to use the browser download location and download images need to show the browser downloads.

Answer 1

not possible to store the image in particular user location due to security issues .you don't force user .you have to suggest him to store particular location .and also you don't know the what file system there in user system.and also downloading path can be setting up by user anywhere so your not able to get that.

Answer 2

$filename = '/images/'.basename($_POST['text']);
file_put_contents($filename, $content);

Answer 3

you have to save/download the image somewhere on your web serwer and next send the file to user using header function, for example:
$file = 'path_to_image';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
else {
echo "file not exists";
}

`<?php
$filename ='http://website.com/images/logo.png';
$size = #getimagesize($filename);
$fp = #fopen($filename, "rb");
if ($size && $fp)
{
header("Content-type: {$size['mime']}");
header("Content-Length: " . filesize($filename));
header("Content-Disposition: attachment; filename=$filename");
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
fpassthru($fp);
exit;
}
header("HTTP/1.0 404 Not Found");
?>`
